It’s not just how you live—it’s when. 🕒

I recently attended a talk by Oxford neuroscientist Professor Russell Foster on his book Life Time. I went in expecting basic sleep tips, but I walked out rethinking my entire daily schedule.

Foster’s work on circadian rhythms shows that our internal body clock regulates far more than just when we feel tired. It’s a master conductor for our entire biology.

Here are the most startling takeaways:

The Dawn Advantage: A walk at sunrise doesn't just wake you up; it "sets" your clock for a better night’s sleep 16 hours later. ☀️

Midnight Snacks: Eating after sundown isn't just about calories; it’s about metabolic timing and weight gain. 🍕

Precision Medicine: The time of day you take your medication can be the difference between a routine day and a life-threatening stroke. 💊

Immune Timing: Even vaccine efficacy can fluctuate based on the hour you’re jabbed. 💉

The Hidden Cost of Night Shifts: The WHO is now recognizing prolonged night shift work as a probable carcinogen. ⚠️

Life Time is a manual for the body you didn't know you needed. It might just change your life.
